Dtd linking

It acts as a wired Ethernet cable link between the two nodes, similar to two devices wired into a router.

Also,  think of the mesh 'node' as a traffic router, like a router on the Internet.  But it has RF and cat5 links instead of fibre cables.   The traffic is data packets going from, e.g. laptops to a website and back, across the mesh network and through many mesh notes or routers.    A user wouldn't want any delay (store and forward) type of capability, rather you want the computer on the other end to be able to respond very quickly (msec).   There is such a thing on the internet as caching information in the network to be more efficient, a type of store.   But we don't do this today on the mesh.
